This report presents 10 patients with Zenker's diverticulum who were evaluated with simultaneous solid-state manometry and fluoroscopy. With this method, intrabolus forces are determined. Each patient had abnormal intrabolus forces regardless of the size of the diverticulum and cricopharyngeal muscle dysfunction. In the literature, there has been conflicting manometry results when studying Zenker's diverticulum. The use of analysis of intrabolus forces increases the sensitivity of manometric evaluation. This study establishes pressure abnormality in the pharyngoesophageal segment of patients with Zenker's diverticulum. The pathogenesis of Zenker's is presented based on these findings.
